HENRY E. MARCHAND, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR OF ONE-HALF OFHIS RIGHT TO WILLIAM J. BEGKFELD, OF SAME PLACE.

AUTOMATIC LIQUID-MEASURE.

SPECIFICATION forming part of Letters Patent No. 232,527, datedSeptember 21, 1880.

Application filed June "23, 1880. (Model.)

To all whom it may concern Be it known that I, HENRY E. MARGHAND, acitizen of the United States, residing at Al legheny city, in the countyof Allegheny and State of Pennsylvania, have invented new and usefulImprovements in Automatic Liquid- Measuring Apparatus, of which thefollowing is a specification.

This invention has for its object to provide a liquid-measuringapparatus which, when set for operation from the outside, will receivefrom a connected source of supply and autol matically discharge adefinite quantity of liquid, the inflowing liquid operating devices forsounding an alarm when a proper quantity has been received, and forregistering the number of measurements.

It is especially dapted for use in measuring oils, molasses, and otherliquids liable to soil the bands and clothing.

It consists, first, in the combination, with the receiving-casing of aliquid-measuring ap paratus, of an inlet-valve and an outlet-valve, afloat arranged to operate said valves automatically through intermediatedevices for closing said inlet-valve and opening said outlet-valve, anda device for opening said inletvalve from the outside of the casing atthe commencement of said measurement, all con structed and arranged forthe accomplishment of desired object, substantially as hereinafterdescribed; second, in the combination, with the receiving-casing of aliquid-measuring apparatus, of an inlet-valve and outlet-valve, and afloat arranged to operate said valves automatieally through intermediatedevices for closing the former and opening the latter simultaneously,and subsequently closing the latter .when a definite predeterminedquantity of liquid has been discharged from the casing; third, in thecombination, with the casing, float, and automatically-operatedmeasuringvalves, of a registering device arranged upon the outside ofthe casing and an operating lever or arm arranged inside the casing inthe path of the float and istering device.

In the accompanying drawings, Figure 1 is a front view "of the apparatuswith some of in dotted lines.

connected with said reg the interior parts indicated Fig. 2 is avertical section 011 line a: a; of Fig. 1. Fig. 3 is a rear view of theapparatus with its back wall removed. Fig. 4 is a horizontal section online 9 y of Figs. 1 and 3. Figs. 5, 6, and 7 are detail views.

The letter A designates the walls of the easing, transversely on thebottom of which is arranged a frame,B, for supporting the valves, valveand alarm operating devices.

0 designates an induction-nozzle passing through the bottom of thecasing and base of the frame B, and having arranged within it a valve,0, Fig.7, which is normally held against a seat, 0, by means of aspring, 0. I

From the valve 0 rises a stem, 0 passing upward through suitable guidepassages formed in the crossbars b and I) of the frame 13, and at itsupper end, which extends above the cross-bar l), the stem 0 has securedto it a horizontal arm, D, extend cross-bar toward the front of thecasing, its front end being widened, and having a vertical opening, d,(see Figs. 5 and 6,) formed through it, to permit the passage of thestem 6 of a valve, E, which normally rests by grav- 7 5 ity upon a seat,0, formed for it at the mouth of the discharge-spoutE, which passesthrough the bottom of the casing and the base of the frame B in the samemanner as does the nozzle O.

The stem 6 is provided with a projecting head, 0 under which is arrangedto take a latch, F, mounted on a pin, f, passing loosely through the armD, and acted upon by a spring, f, to cause the latch to move under saidhead of the stem. Thislatch is provided with a tail, f extendingrearward, for a purpose to be hereinafter explained. For detail view oflatch, see Fig. 5.

A standard, G, projects upward from the 0 top cross-bar, b, ofthe frameB, and through an opening in the arm D, and from this standard Grprojects rearward a short stud, 9, under which is arranged to catch ashoulder, h, formed on a dog, H, pivoted in a slot formed 5 in the armD, and havinga forwardly-extending head, h, which overbalances it tocause it to fall forward by gravity. (See Figs. 2 and 6.)

When the arm D is depressed, thus forcing roo ing above said 70 down thestem 0 and carrying valve 0 away from its seat, the dog H falls forward,and the shoulder h catches under the stud g, thus locking the valveopen. When the parts are thus situated the latch F is caused, by thesprin g f to take under the head of stem 0, as shown in Figs. 5 and 6.

For depressing the arm D a bell-crank lever, I, is pivoted at its angleto a standard, I, mounted on the frame B, the short arm 2' of said leverextending forward over the arm D and provided with a toe, 2', while thelong arm 2' curves upward and terminates in a head or hammer, i arrangedto strike. a bell, 1 From the head or hammer i a loosely-connected rod,70, leads through the front wall of the casing and terminates in a knob,76. When the rod is drawn outward the bell-crank lever will obviouslyact upon the arm D to force it downward. From the top of the frontportion of the frame B rises a standard, I, carrying at its top ahorizontal sleeve, L. Into the rear portion of the sleeve L is fitted acylindrical arm, N, held rigidly in position by a binding-screw, n, andextending rearwardly over the arm D to the middle of the latter. Uponthe rear end of the arm N is fitted loosely a cap, N, in oppositeportions of the wall of which are cut oblique slots 11, into which pinsproject from the arm N, the slots being in such position that when thecap is turned to the right, as viewed from the front, the studs, actingon the walls of the slots, force the cap rearward, when its head orclosed end will strike the head of the dog H and force its shoulder hout of engagement with the stud g, when the arm D will be permitted torise, throwing the bell-crank lever backward,so that the hammer on itslong arm strikes the bell to announce the completion of a measurement.

From one side of the cap N projects a thimble,n ,into which is securedan arm,0, extending from a float, O, and from this thimble a cam, 42projects downward. WVhen this float is caused to rise by the admissionof a liquid into the casing, the cap N is turned on its arm, so as tobeforced rearward, as before described, and when said float has reacheda predetermined point, on being permitted to descend by the drawing offof the liquid, the cam n will strike the tailf of the latch F and causesaid latch to become disei'igaged from the head of the stem 0, so thatthe valve E falls to its seat and closes the discharge-spout. Both thedischarge and inlet valves will then be closed, and the knob must bepulled outward to place the parts in position to commence a11- othermeasurement.

A registering-dial, P, having a marginal series of numbers, is arrangedupon the wall of the casin g, and from the center of this dial ascrewnipple, 19, (see Fig. 2,) extends through the wall of the casing toreceive a nut, P, between which and the dial the wall is firmly clamped,as shown in the sectional view, Fig. 2. Through the nipple p is passed aspindle, Q, carrying at its front end, in front of the dial, a pointer,Q. A pin, q, secures the spindle in the nipple. Upon the rear portion ofthis spindle is rigidly secured a ratchet-wheel, R, and loosely pivotedupon said spindle is a bifurcated arm, S, having its arms 8 s onopposite sides of the ratchet-wheel. Between these arms is pivoted, upona pin, t, a pawl, T, the tongue of which rests upon the periphery of theratchet-wheel at a point slightly above the pawl-pivot, in order to givethe pawl a purchase upon the teeth of the said wheel.

Through the outer end of the lever S is arranged an adjusting-screw, U,the point of which stands in the path of the float O, sothat when saidfloat rises it will strike the screw and raise the lever S, causing thepawl T to turn the ratchet-wheel and spindle Q, thus movingthe pointerin front of the dial to register the number of times the float rises,and consequently the number of measurements made.

The downward movement of the lever S is limited by a stop, 21, fixed tothe wall of the casing, and ,by adjusting the screw U the throw given tothe lever by the float may be so regu lated that the pointer will bemoved the desired distance to properly count on the dial.

It will be understood that the movement of the float may be so arrangedas to cause it to trip the valve-operating and alarm devices when thecasing has received and-discharged any desired definite quantityofliquid, which will form the unit of measurement of the apparatus.

The operation is as follows: The operator draws the rod 76 forward, andthereby causes the toe of the bellcrank lever to depress the horizontalarm D, which, in its downward movement, depresses the valve-stem andvalve 0 0, thereby opening said valve and permitting the liquid to flowinto the casing through the induction-pipe 0. Upon releasing the rod ofthe bell-crank lever the said valve 0 is held open against the upwardpressure of the spring 0 by means of the dogH, which, during the descentof the horizontal arm D, swings forward so that its shoulder h willcatch under the lug or arm 9 of the standard G. While the liquid isflowing into the casing the outlet-valve E is closed by gravity, and asthe liquid rises in the casing the float is caused to rise.

During the depression of the horizontal arm, as just described, thelatch F will be forced by spring-pressure between the said horizontalarm and the head 0 of the valve-stem e of the outlet-valve, as shown inFigs. 5 and 6. As the float rises the cap N will be turned on its arm,the walls of the oblique slots in the cap acting on the pins in saidarm, so that the cap will be forced inward or toward the rear wall ofthe casing, and when the said float has reached a certain height in thecasing the cap N will strike against the dog H, thus freeing the dogfrom engagement with the lug or arm IIO of the dog, which The s rin c uon such disen a einent J P 1 e has heretofore locked the valve 0 in anopen position, immediately forces the said valve up against its seat, soas to cut off the inflow of the liquid, such action necessarily causingthe valve-stem and the horizontal arm D to have a like upward movement.As the arm D risesit acts upon the toe of the bell-crank lever I, so asto cause said lever to strike the gong, and it also raises thevalve-stem 6, so as to open the outlet-valve E. As the liquid now flowsout through the discharge-spout the float descends, and when the saidfloat has reached a predetermined oint the cam a of the thimble nconnected to the slotted cap N,rwill strike the tail f of the latch Fand cause said latch to become disengaged from the head of the stem ofthe outletvalve, thereby permitting said stem and valve to descendinorder to close the dischargespout. Both the discharge and inlet valveswill then be closed, and the knob must be pulled outward to place theparts in position to commence another measurement.

The number of measurements made are indicated by the pointer Q in frontof the dial P, as hereinbefore described.
